Description
The RIK-2 monoclonal antibody specifically binds to CD253, also known as TRAIL (TNF-Related Apoptosis-Inducing Ligand) and Apo2 ligand (APO-2L). CD253 is a member of the Tumor Necrosis Factor Superfamily and is encoded by the TNFSF10 gene. CD253 is a type II membrane protein that may be expressed as a soluble as well as full-length, cell surface-associated protein. Both surface and soluble forms of TRAIL rapidly induce apoptosis in a wide range of tumor cell lines but not normal tissue. TRAIL is expressed by activated T cells, NK cells, dendritic cells, monocytes and a variety of non-lymphoid cells. TRAIL can bind to and exert apoptosis through DR4 (TRAIL-R1) and DR5 (TRAIL-R2) receptors. It can also bind to decoy receptors, including DcR1/TRID/TRAIL-R3 and DcR2/TRUNDD/TRAIL-R4, and possibly OPG/TNFRSF11B, which may serve to regulate TRAIL activity. TRAIL has been shown to be involved in T cell-mediated cytotoxicity, but its mechanism of action remains to be fully elucidated. The RIK-2 clone was selected based on its ability to block TRAIL-mediated cytotoxic activity.
Immunofluorescent Staining and Flow Cytometry: Applications include flow cytometry (0.25-1.0 µg/1x10e6 cells). Blocking: The RIK-2 antibody is useful to block TRAIL-induced apoptosis. The no azide/low endotoxin format (NA/LE), Cat. No. 550912, is recommended for in vitro blocking assays.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.

3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
